EXHAUST DEFLECTOR FOR TRACTORS Filed June 16 1927 W5: im! allllllll IN VEN TOR BY 1Q; Cqraa Bar/(e6 ATTORNEY Patented Dec. 3, 1929 EXHAUST DEFLECTOR FOR TEACTOR$ Application filed June 16,

This invention relates to a new and useful device in the nature of an exhaust deflector particularly adapted for tractors, as a means of deflecting the exhaust gases from the motor 5 employed to operate the tractor.

The object of the invention is to provide an exhaust deflector of novel construction and arrangement of parts, hereinafter more fully described, claimed and illustrated in. the accompanying drawing.

Fig. 1 is a front elevational view of my improved exhaust deflector.

Fig. 2 is a rear elevational view thereof.

3 is a vertical central sectional view illustrating a modification of my improved device.

Fig. 4 is a front elevational view illustrating; a modification of my improved device.

5 is a further development of my improved device.

As here embodied my improved device comprises a receptacle 10, of box shaped construction, having an open upper end, covered by a screen member 11, attached to a rim member 12, adapted to engage the sides of the above mentioned open upper end 01"? the receptacle 10. The rear portion of the receptacle 10 is provided with an opening, having an outwardly flanged element 13, adapted to receive one extremity of the elbow member 1 1. The elbow member 14: is of the usual 90 de gree type, and is adapted to engage inv the extremity of the exhaust pipe 15 of the motor adapted to be used in a tractor. The extrem- 5 ity of the exhaust pipe 15 is somewliiat enlarged, as at 16, so as to limit the engagement of the elbow member 141. The clamping member 17, of ring shaped construction, is adapted to encircle the enlarged extremity 1t. of the exhaust pipe 15, and is provided with apertures, at its extremities, adapted to receive the threaded member 18, a machine screw, belt, or the like, and the usual nut 19, as a means of contracting the enlarged extremity 16 of the exhaust pipe 15, as a means of securing my improved. device in place. A. screen 20 is mounted within the receptacle 10 and arranged for assuming various inclined positions.

The above described construction is such 1927. Serial No. 199,286.

aswill permit the screen member 20 to function as a spark arrester, in event my improved device is attached to a comparatively short exhaust pipe. The above described construction is also such as will permit the receptacle 10, to deflect the exhaust gases upwardly, away from, or out of contact with the operator oi? the tractor to which same is attached.

I have shown the frame member 21, provided with elongated apertures 25, formed at the sides thereof, at or near its upper portion. The rod 26 is adapted to engage in the elongated apertures 25, and is secured to the sides of the receptacle 10, as a means of pivot-ally and slidably mounting the screen member 20, in the receptacle 10. The rod 2? is pivotally attached, at its upper extremity as at 28, intermediate the screen member 20, and extends downwardly therefrom. The rod 27 provided with a threaded lower portion 29, engaging in a threaded aperture formed in the adjusting member 80. The adjusting member 30 is provided with an enlarged head 31, posh tioned outside the bottom oi the receptacle 10. The adjusting member 30 is rotativcly mounted in the bracket 32, attached to the bottom of the receptacle 10. The collar 33 is attached to the adjustingmember 30, as a means of holding the adjusting member 30 in place in the bracket 82.

The above described. construction is such as will permit the screen member 20 to be positioned at any desired angle when the enlarged head 31 of the adjusting member 30 is turned or rotated.

In Fig. 1 of the accompanying drawing, I have shown my improved device provided withan aperture at the bottom thereof, having; an outwardly flanged portion 8 1, as a means of directly attaching my improved device to the above mentioned exhaust pipe 15. The receptacle 10 is provided with a trustum conical top member 35. A screen member 36 is attached to one side of the receptacle 10.

In Fig. 501: the accompanying drawing, I have shown a disc member 11, secured to the central portion of the screen member 11, which is provided with an aperture to accommodate the said disc member 41. A similar disc member 42 is pivotally attached, at its center to the center of the disc member 41. The disc member 42, has formed therein radial elongated apertures 43, adapted to register with similar apertures 44 formed in the disc member 41. The above described construction is such as will permit the rate of flow, ordischarge of the exhaust from the motor to be regulated, as may be desired.

, Having thus described my invention what I claim as new and desire to protect by Letters Patent of the United States is as follows:

1. An exhaust deflector of the class described, comprising an exhaust receptacle having an inlet opening and a top exhaust opening, a deflector within the receptacle, and

extending across the inlet opening at an inclination, a screen closing the said top exhaust opening, loop members formed at the sides near the top of the deflector to pro vide elongated apertures, a rod engaged thru the apertures and secured to the sides of the receptacles, a second rod pivotally attached at one of its ends to the said deflector, and extending downwardly therefrom, an adj usting member threa'dedly engaged to the hottom of the said second rod, and means for rotatively connecting the adjusting member with one side ofthe receptacle.

2. An exhaust deflector of the class described, comprising an exhaust receptacle having an inlet opening and a top exhaust opening, a deflector within the receptacle, and extending across the inlet opening at an inclination, a screen closing the said top exhaust opening, loop members formed at the sidesnear the top of the deflector to provide elongated apertures, a rod engaged thru the apertures and secured to the sides of the receptacle, a second rod pivotally attached atone of its'ends to the said deflector, and extending downwardly therefrom, an adjusting member threa'dedly engaged to the bottom of the said second rod, and means for rotatively connecting the adjusting member with one 'side of the receptacle, consisting of a bracket attached to the receptacle,

the adjusting member being rotatively mounted in the bracket, said. adjusting member also being formed with an enlarged head, and a collar attached to the adjusting member, and abutting the bracket. 7

In testimony whereof I have aflixed my signature.
